Redis MCP server

Last verified: 2026-09

Get and set keys in Redis.

Official reference Databases & data Needs a secret Claude Desktop, Cursor, Windsurf, Claude Code, VS Code

What it does

Get and set keys in a Redis instance. Useful for inspecting a cache. A FLUSHDB-capable connection is a production outage waiting for a bad tool call.

It sits in Databases & data: A database MCP is SQL or an API with your credentials.

Good for

Get a cache key the app is supposedly setting.
See whether a session or rate-limit key exists.
Debug a queue length without redis-cli.
Set a key only on a disposable Redis, never prod.

Tools

get / set / list keys — Read and write the keyspace the URL can see.

Config (Claude Desktop / Cursor / Windsurf)

Paste the JSON below. Same mcpServers shape. Replace placeholder paths and secrets. Windows paths look like C:\\Users\\you\\project, not /path/to. Host-side steps →

Claude Desktop

OS	Config file
macOS	`~/Library/Application Support/Claude/claude_desktop_config.json`
Windows	`%APPDATA%\Claude\claude_desktop_config.json` (usually `C:\Users\<you>\AppData\Roaming\Claude\`)
Linux	`~/.config/Claude/claude_desktop_config.json`

Cursor

Scope	macOS / Linux	Windows
This project	`.cursor/mcp.json` in the repo root
This user	`~/.cursor/mcp.json`	`%USERPROFILE%\.cursor\mcp.json`

Windsurf

OS	Config file
macOS / Linux	`~/.codeium/windsurf/mcp_config.json`
Windows	`%USERPROFILE%\.codeium\windsurf\mcp_config.json`

{
  "mcpServers": {
    "redis": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-redis",
        "redis://localhost:6379"
      ]
    }
  }
}

Windsurf remote MCP: use serverUrl instead of url if the block below is HTTP.

One-liner: npx -y @modelcontextprotocol/server-redis redis://localhost:6379

Secrets it wants: REDIS_URL

How to get started

Use a Redis ACL user that cannot FLUSHALL / CONFIG.
Point the URL at a dev instance first.
Ask the model to GET a known key before you let it SET.

Access risk

SET and flush operations are destructive. Network-exposed Redis without a password is worse.

When to skip it

Skip it unless you actually debug Redis. Do not attach prod Redis to a general-purpose chat.

Instead: PostgreSQL, Filesystem.

OfficialPostgreSQLRun SQL against a Postgres database. OfficialFilesystemRead and write files inside a folder you choose.

FAQ

Is Redis just get/set?

The official server is a thin key surface. It is not RedisInsight.

What if I point it at prod?

FLUSHDB and key deletes are one confused prompt away if the URL allows writes. Use a replica or a local instance.

URL in the args?

Yes — redis://... after the package name. That URL is a secret.

Redis or Postgres?

Cache/session vs relational. Different data.
